Overview
180° reverse bending of wire specimens
The machine is used for bending fatigue tests on wire specimens. The wire is bent 90° to the left and 90° to the right, a total reverse bending movement of 180°.
The lower end of the wire is clamped into a screw terminal and guided through bending cylinders, which define the bending radius according to the wire diameter. The upper end is clamped into a movable bending arm driven by a servomotor.
The machine is adjustable according to the relevant standards, and specimen breakage is detected by electrical conductivity.

Applications
Where the wire bending tester is used
Up to 3 specimens
Three wires of the same diameter tested at once for diameters from 0.3 to 2 mm.
Flex life (Tick Tock) tests
Repeated 180° bending until fracture, with the cycle count at fracture displayed.
Wire quality control
Bending fatigue checks on round, straightened wire products up to 2,000 MPa.
Features
Test principle and control
Test principle
- Bending 90° left and 90° right, 180° in total.
- Bending angle deviation max. ±3°.
- Exchangeable bending cylinders define the bending to the wire diameter.
- Servomotor-driven bending arm, max. 180° bending per second.
Capacity
- 3 specimens for wire diameters 0.3 mm to 2 mm.
- 2 specimens for 2 mm to 5 mm, 1 specimen from 5 mm.
- All specimens tested together must have the same diameter.
Control and machine
- Operator enters number of cycles and bending speed.
- Digital display of cycle counter and cycles at fracture.
- Break detection by electrical conductivity.
- 1030 x 800 x 1385 mm, approx. 300 kg, 400 V / 50 Hz, 4.0 kW.
Benefits
Why use this tester
Wire fatigue data. Tests wire flexibility and resistance to repeated bending.
Shorter test time. Up to 3 samples can be tested at the same time.
Adaptable to diameter. Exchangeable bending rollers suit different wire diameters.
Controlled bending. The servomotor drive gives a controlled bending movement.
Automatic monitoring. Break detection helps automate test monitoring.
Standard testing. Supports wire testing to ISO 7801 and DIN EN ISO 15630.
